Robin psc-loop tester

[Mfctitch]

Evening everyone
Have got hold of an robin kmp4120DL loop tester and need some advise.which has a three lead
When trying to carry out a PSCC test the manual says put the green lead on the neutral. but if I do put it on the neutral bar then put the probes on the incoming phase and neutral I just get a "HI" reading.
The only way to get a proper reading is to turn the main switch on which of course you are not supposed to do with the main cover off.

So I have two questions:
First what stupid thing am i doing wrong.

Second does any one know of any videos on the use of this and any of the other robin test meters.

Thanks in advance.

Put the green lead on the earth bar. By having it on the nuetral bar and the main switch off then the green lead is connected to nothing really as the nuetral bar is isolated.

Cheers for reply
but I'm under the impression that you put the green lead on the earth bar to get the PFC?

The green lead goes on the earth bar for all tests

That's correct.

With my fluke to get PSCC I 'piggy-back' N+E and connect to Neutral. Main switch has to be closed i.e. live test.
Edit - Wasn't thinking - Obviously Main switch open and test on live side.

Now I'm lost :-(
if to get the PFC you connect the green to the earth bar and put the probes on the incoming phase and neutral.
How will you get the PSCC if you still leave the green lead on the earth bar?

 

[Geoffsd]

No - in other words connect both N and E lead to Neutral conductor.

My Earth lead has a stackable facility into which you insert neutral lead, so connecting them both together.

 

[Mfctitch]

Oh so you're saying put one probe on the incoming phase and then connect the earth lead and the neutral lead together and put this lead on the incoming neutral?
my problem is that with the robin leads i can not do that the earth lead has a fixed clip on it.
the phase and netural leads can be swapped for between probes and clips but i can not attach the clip to the probe.
if it helps Google robin test lead SL 16E.

Oh so you're saying put one probe on the incoming phase and then connect the earth lead and the neutral lead together and put this lead on the incoming neutral?

Yes.

Have had a look on Google. Does the earth croc not pull off? If not I suppose you will have to get another set if you want to test PSCC.

 

[Mfctitch]

Ok Will check with robin if they do such a set

Robin is Kewtech or vias versa, I didnt have the manual for my robin and after a bit of geeking up i found kewtech is the same.
The Green lead ALWAYS goes in the earth bar! If your doing PFC surely you should have Earth lead to earth bar and both the others to Line?
You only put the "Spare" lead on so its not dangling around live while your doing the test, When doing PSCC you only put the earth lead on the earth bar so its not dangling around like the test before(not that it would be live).
I mite be wrong.
I think its just good practice not to have leads dangling around when your live testing.
My robin has 2 or 3 set leads so i just do as above if iv got the 3 lead in. Hope this helps.

 

[Hawk81]

That is what I said way at the start and I was shot down.

 

[Electro-tech]

Exactly ! and Robin is now Fluke.

If all else fails read the instructions.
